I was told (or read... I can't remember now!) that keeping a young male dog away from smelling vertical surfaces where other dogs have marked will make it more likely that they will continue to squat (or Kodi doesn't squat, he stands like a little horse, but he doesn't lift his leg) rather than lifting their leg.
I am very careful about this, and don't let Kodi sniff around vertical surfaces when we are out on walks in heavily trafficed areas. He can have all the sniffing time he wants, off leash in the woods or on our property.
He does not lift his leg to pee, and he is now 2 1/2. However, I know that he understands and CAN mark, because I'veseen him do it a few times when we've been at dog shows, and there has really been no other place to let him go other than where lots of other dogs have been. In these cases, I've seen him lift his leg and "mark" even on tall grass and weeds. Hey, when you are short, LOTS of things look like vertical surfaces!
I have to say that my experience with a Hav in long coat is that leg lifting is mess-making. It doesn't matter how high he lifts his leg, he ends up peeing on his hair.
He also uses a litter box in the house, and I think THAT would be problematic with a dog who had to lift his leg to pee!
Finally, I have walked with several people whose male dogs feel the need to mark all the time, and it seems to me that they save up urine for this. It takes FOR EVER to get them to empty their bladder. With Kodi, I say, "Go pee," and we get the job done in seconds and can get back to showing, or get back in the car or just enjoying our walk.
So I, for one, will continue to encourage what he does now, and limit the chances for leg-lifting and marking as much as possible.
